sdhci_pci module is blocking low power s0ix sleep with GL9767

kernel.log s2idle without and with sdhci_pci module

S2idle sleep on TUXEDO InfinityBook Pro 14 Gen9 Intel laptop with GL9767 SD card reader consumes 6 watts. Intel Core Ultra 7 155H is not entering s0ix properly. If I blacklist sdhci_pci in /etc/modprobe.d/blacklist.conf then the device sleeps with 1.2 watts (this is not super good, but OK). Unfortunately unloading and reloading does not work either. Once the module has been loaded, the high power consumption remains, even after a rmmod.

I tested this behavior with linux mainline 6.11.0-rc7, 6.11.0-rc7-next-20240909. Kernel mmc/next does not work either.

I also used Intel S0ix Selftest Tool and it blamed the GL9767 SD card reader.

I was able to reproduce the behaviour with kernel v6.11.

I have InfinityBook Pro 14 Gen9 AMD and have troubles with going to sleep and back.

After debugging suspend using this instruction https://www.kernel.org/doc/html/latest/power/s2ram.html I found this logs in dmesg:

I have no idea which information could be helpful, but I'm willing to provide any needed info.

I'm sorry, I didn't provide the exact description of "troubles" I mentioned. For me, after going to sleep, I can not resume. The laptop just boots starting from grub menu.

Well, I must admit I'm not used to think before I write. Modern platforms that allow to edit your messages made me lazy.

Some more info on the topic:

I've tested suspend on tuxedo kernel:
$ uname -a
Linux tuxedo-inf9 6.11.0-107011-tuxedo #11tuxnoble1 SMP PREEMPT_DYNAMIC Sat Nov  9 11:02:15 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

After that I found a public thread with a patch to the problem of the topic starter: https://www.spinics.net/lists/linux-mmc/msg82920.html

I'm not sure how to check the code of the 6.11.0-107011-tuxedo kernel, yet I found that this patch is applied on the latest kernel version 6.12.5
I copied configs of the tuxedo kernel and build a 6.12.5 kernel with "make -j bindeb-pkg"

Unfortunately, s2ram still gives me the same problem: system can not go to sleep properly and just turns off. Blacklisting sdhci module didn't help, I still see the same messages in dmesg.

sdhci_pci module is blocking low power s0ix sleep with GL9767

[Georg Gottleuber]

Hello,

I have a problem with s0ix sleep on a laptop with GL9767 SD card reader.

The device is a TUXEDO InfinityBook Pro 14 Gen9 Intel laptop and 
consumes 6 watts in s2idle (not reaching s0ix). If I blacklist sdhci_pci 
in /etc/modprobe.d/blacklist.conf then the device sleeps with 1.2 watts 
(this is not super good, but OK). Unfortunately unloading and reloading 
does not work either. Once the module has been loaded, the high power 
consumption remains, even after a rmmod.

I tested this behavior with linux mainline 6.11, 
6.11.0-rc7-next-20240909. Kernel mmc/next does not work either.

In an AMD device (InfinityBook Pro 14 Gen9 AMD), however, the same card 
reader sleeps without any problems.

Any ideas?

Kind regards
Georg Gottleuber

I am sorry, but I don't have any useful suggestions at this point. We
need some help from the guys from Genesys Logic.
